Understanding Lab Tests for Pulmonary Disorders
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Pulmonary disorders encompass a wide range of conditions affecting the lungs and respiratory system, including asthma, COPD, pneumonia, pulmonary fibrosis, and lung infections. Most pulmonary conditions are primarily diagnosed through imaging studies, pulmonary function tests, and physical examination. However, blood testing plays a fundamental role in assessing overall health, identifying underlying infections, and monitoring complications that may contribute to respiratory symptoms.
Recommended Test
Human T-Cell Lymphotropic Virus I, II (HTLV-I/HTLV-II), Qualitative
This test detects the presence of HTLV-I and HTLV-II viruses in the blood. While rare, HTLV-II infection has been associated with certain pulmonary disorders in some cases. Although the exact connection is not fully understood, testing may be considered when investigating unexplained respiratory symptoms, particularly in patients with risk factors for HTLV exposure.

Why Blood Testing Matters for Pulmonary Health
While there isn't a single blood test to diagnose most lung conditions, laboratory testing is essential for detecting viral infections, inflammatory markers, and other systemic factors that can affect respiratory function. Certain viral infections, though rare, have been associated with pulmonary complications and may require specialized testing to identify.
Understanding the Role of Specialized Testing
HTLV testing is typically considered in specific clinical situations where there may be an association between viral infection and pulmonary symptoms. This type of testing is usually ordered by healthcare providers when conventional diagnostic approaches have not provided clear answers and there is clinical suspicion of viral involvement in respiratory complications.
